No free space

A friend had trouble with his Dell desktop computer. To try to fix it he used a Win7 disk from his son's laptop. Later he found his restore disk and tried to run. Disk won't run because it generates an error message - no free space.

Is your friend able to get into Windows at all? Or perhaps Safe Mode? If so, then you can check to see if there is free space on the hard drive. If necessary, delete some stuff.

If he can't get into either Windows or Safe Mode, perhaps he can get into Safe Mode Command Prompt, the most stripped down mode for Windows. Here you can check to see if the hard drive is filled up, but you'll need to use DOS commands to do it.
